Seagate Desktop HDD 4TB Review: Big Capacity At 5900 RPM

Results: Data Throughput And Interface Bandwidth

As we expected, Seagate's Desktop HDD.15 ST4000DM000 isn’t as fast as the Barracuda 7200.14. The difference isn’t really that large, though, and an average 132.2 MB/s sequential read speed and 131.5 MB/s sequential write speed is enough to put the new drive in second place for both benchmarks. This also means the 4 TB Desktop HDD beats several 7200 RPM competitors, like Western Digital's Black WD4001FAEX and the Hitachi Deskstar 7K4000.

The Desktop HDD.15 ST4000DM000 can't quite hit the 180 MB/s transfer rate that Seagate promises in our h2benchw benchmark. Its 167 MB/s are still very respectable, though.

Of course, because we're using the same SATA 6Gb/s interface as the one used on the Barracuda drives, we end up with similar performance across the wire (even though this is primarily a measure of the drive's cache).

    Would rather take 3TB @ 7200 over 4TB @ 5800, I'm sure people would agree with that.

    Good Read.
    Noticed a small insignificant error in the "Drive Surface Temperature" chart. It lists the 4TB HDD.15 as a 7200rpm drive rather than a 5900rpm one.

    Now that everyone has a full lineup of 4TB drives out, how about finally releasing something larger?
    Bring on the 2160p content!

    the thing is this hard drive geared towards speed it's mostly geared towards data storage, which is why it's only 5800rpm, so you wouldn't get this obv if you want fast read and write times, that's what SSD's are for.

    The one graph, about temperatures, said "higher is better" beneath it...

    Great media storage drive for those with SSDs as boot drive which is what is currently on the trend right now.

    To all the people who say performance is not important, I would like to remind them we don't have a 4 terabyte SSD yet, and until then, if I need 4TB I have to use a hard drive. And it better be a fast one or I will be sitting for ever in a loading screen in-game, opening big programs and loading 8GB of sample sounds to RAM when I work with music.

    For me this is a big mistake for Seagate. I always bought their drives because they were the fastest, but it seems they are now joining the WD green lineup. I'll probably have to go with hitachi now to have some decent speed.

    I personally only care about price / gigabyte. Give me the ability to store more HD pron and I'm happy. Don't care if it dies...

    Would anyone use a 4TB drive as a system drive anyway? Short stoked to 200GB maybe but otherwise......? Reliability has never been a strong point with drives over 1TB IMO.

    I just see these big drives as a huge liability really, but folks will hoard their data.
